11, AugustMost padded and upholstered seats or seat backs used in the transportation industry are assembled with a solvent based contact adhesive. In this process the fiberglass or steel base of a seat or seatback is bonded to foam, which is then bonded to re-enforced fabrics, and finally covered with cloth. Due to the high traffic of these seats, they typically have a seven + year duty cycle. Given these conditions it is often required that lamination between these substrates be permanent.
Most assembly and recovering companies that perform this service are looking for alternatives to flammable spray products such as contact cement. Along with the need for adhesive alternatives, the need to have easier removal of the foam cushioning from the fiberglass or steel bases has been expressed.
Glue Machinery proposes that PUR reactive hot melt is a good alternative. It is easily sprayed onto one side of each component, it bonds quickly, and it cures to a very strong bond. When it is time for this component to be re-upholstered, the materials can be removed with high heat as the PUR bond is softened at temperatures over 300 F.
PUR is also available for smaller jobs or spot welding in 10 ounce cartridges, which are processed by PUR Cartridge Spray guns. For larger volume applications the heated five gallon pail unloader TOF20 Mini with heated swirl hose and handgun is used to dramatically increase output and cut the cost of the PUR hot melt.
